Preparation of Imide Oligomers via Concurrent Reactive Extrusion [PDF]

open access: yes
Reactive extrusion can be used in a continuous, solvent-less preparation of imide oligomers involving two competing reactions among three ingredients, the first reaction between a dianhydride and a diamine and the second reaction between an endcap and ...

Planar Chirality Controls Diastereotopicity in [2.2]Paracyclophanyl Cyclopropenes

open access: yesChemistry – A European Journal, EarlyView.
In this work, we report the synthesis of [2.2]paracyclophane‐substituted cyclopropenes via rhodium‐catalyzed cyclopropenation using a pCp‐derived carbene precursor. The planar chiral framework induces diastereotopic differentiation of otherwise equivalent alkyl substituents, which is reflected in their 1H NMR spectra.

Unlocking Heterobimetallic Architectures in a Symmetric PNNP Ligand Environment

open access: yesChemistry – A European Journal, EarlyView.
A symmetric PNNP ligand enables the modular assembly of heterobimetallic ZnRu and CoRu complexes from a mononuclear Ru(II) precursor. Ligand deprotonation triggers dearomatization and contraction of the metal–metal distance. Combined DFT and QTAIM analyses reveal metallophilic interaction in CoRu but not in ZnRu, highlighting controllable geometric and

Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst

open access: yesChemistry – A European Journal, EarlyView.
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

Iridium Complexes of a Triazole‐Derived Pincer Ligand: Synthesis, Reactivity, and Transfer Dehydrogenation Catalysis

open access: yesChemistry – A European Journal, EarlyView.
Ir pincer complexes bearing a triazole architecture in the pincer backbone and O‐ancillary chelating ligands are presented. These were employed in the catalytic transfer dehydrogenation of alkanes as well as of saturated heterocycles. Reactivity of these complexes with silver salts and Lewis acids produced various cationic iridium complexes.
